Urinary incontinence is a debilitating condition for elderly inpatients. The etiology is not well understood and has not been investigated extensively. Incontinence volume per episode has been shown to vary within patients and does not appear to be associated with cystometric bladder capacity. The objective of this study was to determine the relationship of residual urine volume following involuntary voiding to the incontinence volume and the total bladder volume in elderly inpatient men. Sixteen patients had catheterized residual urine volume measurements done following involuntary voiding on each of four days. Significant variability was found in the residual urine volume, the incontinence volume, and the total bladder volume within patients having urinary incontinence. The variability observed in volume parameters suggests that factors other than intravesical volume may have a significant role in the etiology of involuntary voiding in elderly patients.
